[RA]: Fixing i686 bootstrap failure because of pushing the equivalence patch
GCC with my recent patch improving cost calculation for pseudos with
equivalence may generate different code with and without debug info
and as the result i686 bootstrap fails on i686. The patch fixes this
bug.
gcc/ChangeLog:
PR rtl-optimization/112107
* ira-costs.cc: (calculate_equiv_gains): Use NONDEBUG_INSN_P
instead of INSN_P.
